IMPROVEMENT IN LOOMS FOR WEAVING WIRE-CLOTH.

Specification forming part of Letters Patent No. 131,584, datedSeptember 24, 1872.

To all whom it may concern:

Be it known that we, GEORGE F. WRIGHT and CALEB K. SAWYER, of Clinton,in the county of Worcester and State of Massachusetts, have inventedcertain new and useful Improvements in Looms; and we do hereby declarethat the following is a full, clear, and exact description thereof,reference being had to the accompanying drawing and to the letters ofreference marked thereon, which form a part of this specification.

Our invention relates particularly to that class of looms used to weavewirecloth, but we do not wish to be understood as confining ourselvesexclusively to that class of looms, as our improvements may perhaps,with equal advantage, be applied to looms for other purposes.

The nature of our invention consists in the combination of theback-reed, whip-roll, and pressure-roll, all hung upon two leverspivoted on the sides of the loom.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which--Figure 1 represents a side elevation, and Fig. 2 a plan view.

J J represent two levers pivoted one upon each side of the loom, thelower ends bearing against a hook or projection, 43, upon another lever,K, also pivoted one upon each side of the loom, and the front ends ofsaid leversK K are pressed down by a spring, 70 The upper ends of thelevers J J have in their center bearings for the whip-roll L, and infront of said roll, attached to the levers, is a reed, M. In rear of thewhip-roll L is placed a pressure roll, N, covered with rubber or othersuitable material. This roll is placed in movable journal-boxes min thelevers J, and pressed against the whip-roll by set-screws a bearingagainst theboxes m. The warp-wires pass up between the rolls L N, overthe former, and through the reed M. The pressure-roll N is intended toroll with and against the whip-roll, being pressed against it firmly, toprevent the warpwires from flying back any further when they break inthe operation of weaving, and the back-reed M serves to show at oncewhich thread is broken, and keeps every wire in a straight line to theharnesses.

Having thus fully described our invention,

what we claim as new, and desire to secure by Letters Patent, is-

The combination of the back-reed M, whiproll L, and pressure-roll N, allhung upon two levers pivoted on the sides of the loom, substantially asherein set forth.

In testimony that we claim the foregoing as our own we aflix oursignature in presence of two witnesses.
